It was discovered that containerd insufficiently restricted permissions on container root and plugin directories. If a user or automated system were tricked into launching a specially crafted container image, a remote attacker could traverse directory contents and modify files and execute programs on the host file system, possibly leading to privilege escalation. (CVE-2021-41103)

It was discovered that containerd incorrectly handled file permission changes. If a user or automated system were tricked into launching a specially crafted container image, a remote attacker could change permissions on files on the host file system and possibly escalate privileges. (CVE-2021-32760)
